Point this webhook at the API Workflow you created in the previous step, and in the API Workflow, set up the workflow by pressing "Detect Data" while testing the Persona plugin on your test page. The URL to point the webhook at will look something like this, and you can copy it after you've pressed "Detect Data": https://withpersona.bubbleapps.io/version-test/api/1.1/wf/persona_inquiry_created/initialize
